I want to buy the brightest flashlight for a given number of a type of battery. How can I do that?
I would also like to have some way to determine what how types and numbers of batteries compare. For example, which would be more powerful? A flashlight that uses 2 C batteries or one 4 that uses 4 AA? How many D or C bateries are equivilent to a lattern battery? I’m talking about alkaline batteries or rechargeable NIMH AA or AAA. I don’t think I’ve seen an alkaline lattern battery. Thanks
